Total Knee Arthroplasty in People with Hemophilia: Higher Incidence of Periprosthetic Joint Infection and 1-Year Revision/Re-Operation than the General Population and Lower Prosthetic Survival When Early Postoperative Bleeding Complications Occurred: Current Literature Review

: The purpose of this narrative review of the recent literature is to analyze the outcomes, complications, and implant survival of total knee arthroplasty (TKA) carried out on people with hemophilia (PWH). It has been shown that TKA substantially alleviates preoperative pain and improves knee function and the patient's quality of life. However, the complication rates of TKA range between 8.5% and 28.7, with postoperative hemarthrosis being the most frequent (7.6%). Besides, when comparing if the TKA was implanted before or after the year 2000, a reduction was found in the rates of periprosthetic joint infection-PJI (6.2% to 3.9%) and aseptic loosening (3.8% to 2.1%). Comparing prosthesis survival between PWH who had suffered early postoperative bleeding complications (EPBC) and patients who did not suffer EBPC, the mean survival duration was 17 years for the EPBC group and 22.1 years for the non-EPBC group. Survival rates were 80% for the EPBC group and 96.4% for the non-EPBC group. Compared to patients without hemophilia, PWH had a substantially higher incidence of PJI (Odds Ratio-OR 1.6) and 1-year revision/re-operation (OR 1.4). In short, although TKA substantially improves the quality of life of PWH, it is an intervention that has a non-negligible percentage of complications. TKA in PWH should preferably be performed only in highly specialized centers for the orthopedic treatment of hemophilia.
